Dioscorea sp. (Dioscoreaceae) , 47564. Yam. FromBahia, 
Brazil. Tubers presented by Mr. V. A. Argollo Ferrao. 
" ' Inhame figado de plru, ' or 'caissara' [turkey-liver 
yam, - on account of the shape of the aerial tubers]. 
This very interesting inhame is cultivated here in 
some localities but is rare and is not found in the 
markets. The tubercles are borne on the vine. I had 
a few last year and planted them in December, when 
they were starting. I am now (April 28) picking the 
crop. The tubercles I have eaten were boiled and I 
found them very good. I think it is a plant worth propa- 
gating, for it gives an excellent substitute for the 
potato, is productive, and the tubercles keep for 
several months without deterioration." (Argollo.) 
DoUehos lablab (Fabaceae), 47568. Bonavist bean. From 
St. Vincent, B. W. I. Seeds presented by Prof. S. C. 
Harland, assistant for cotton research, Agricultural 
Experiment Station. " ' St. Vincent Bush. ' I discovered this 
type in a peasant's holding in St . Vincent in the spring 
of 1915 and found that it bred true when put into 
pedigree culture. Under cultivation it produces a 
wiry bush of from 1% to 2 feet in height, and bears a 
heavy crop when environmental conditions are favora- 
ble. As a cover crop for orchards in Florida I think 
it is worth a trial. With me the plants of the bush 
Dolichos always flower when 5 weeks old and ripe pods 
are produced at 8 weeks. Often a second crop of pods 
is produced. The beans are quite palatable, though 
they are inferior to Lima beans. I should mention 
that in the course of my inheritance studies on 
Dolichos, I have established that the bushform behaves 
as a simple Mendelian recessive to the climbing form. 
In a cross between *St. Vincent Bush' (white) and 'Purple 
Soudan' climber, I have isolated pure bush types of 
varying vegetative habits. Some are much more vigorous 
than the original bush parent. I have also succeeded 
in isolating a burl, form of 'Vilmorin's Stringless,' 
by crossing 'Stringless,' with the native bush."

Hymenaea eourbaril ( C a e s a 1 p i n :i a c e a e ) , 47559. Courbaril. 
From Puerto Cabello, Carabobo, Venezuela'. Fruits 
presented by Mr. J. G. Meyer, American vice consul. 
This important tree flourishes throughout the tropical 
parts of the western hemisphere. The pods contain an 
edible substance surrounding the seeds, and the wood 
is fine grained, hard and heavy. The principal use of 
the tree is in furnishing South American copal, - a
